Reliable Protection for Critical Loads
The UPS integrates output overload protection, output short-circuit protection,
inverter over-temperature protection, low battery warning and battery overcharge
protection. These functions help improve system stability and protect connected
equipment from power interruptions and abnormal power conditions.
Intelligent Monitoring and Management
The LCD display shows UPS operating status, parameters and alarm information
in real time. RS232 / RS485 communication interfaces and optional SNMP network
adapter allow remote monitoring through UPS management software.
High Environmental Adaptability
The circuit boards are installed in an enclosed structure and treated with
protective conformal coating, making the UPS suitable for demanding environments
such as tunnels, squares, industrial facilities and communication sites.
